Abstract

PURPOSE: To achieve the improvement in the light utilization efficiency of incident laser light by disposing multilenses in front of parallel driving acousto-optic element.
CONSTITUTION: The incident laser light 5 from a laser light source is split to plural beams 5A by multilenses 7, and the respective beams 5A are focused on the focusing plane 13 of the transducers 3 of acousto- optic elements 1, whereby the plural beams 5A are simultaneously modulated. The modulated beams 5B having passes through the acousto-optic element 1 are suppressed of spreading by a second lens 12 and are entered to a light scanner 8. The beams 5C having been polarized in the light scanner 8 are condensed by a condensing lens 9 and are led to a photosensitive drum 11. The disposition of the multilenses in front of the parallel driving acousto- optic elements in this way enables the utilization efficiency of the incident laser light to be improved.
